Highly effective silicone-based defoamer for rapid foam knock-down and long-term foam suppression.
Excellent compatibility with water-based systems, including acrylic, vinyl acetate, and styrene-butadiene emulsions.
Low dosage requirement—effective at 0.05–0.3 wt% in most polymerization and coating formulations.
Thermally stable up to 120 °C, supporting use in high-temperature reaction and processing conditions.
Non-yellowing and non-staining, preserving clarity and color fidelity in sensitive end applications.
Emulsion polymerization (e.g., SBR, VAE, acrylic latices).
Architectural and industrial waterborne coatings and paints.
Adhesives and sealants manufacturing, especially pressure-sensitive and construction-grade formulations.
Textile sizing and finishing baths where foam interferes with uniform application.
Water-based cleaning and metalworking fluid concentrates.
